Given numbers are 829, 644, 978, 263

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(829, 644) = 533876

GCD(829, 644) = ( 829 x 644 ) / 533876

= 829 / 644

= 829

Step2:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

Step3:

LCM(1, 263) = 263

GCD(1, 263) = ( 1 x 263 ) / 263

= 1 / 263

= 1

So, Greatest Common Divisor of 829, 644, 978, 263 is 1
